自动打铃系统 附带时钟 定时打铃 整点打铃

说明：  这是8位CPU的CVDL代码。CPU 的主要功能是执行指令，控制完成计算机的各项操作，包括运算操作、传送操作、输入/输出操作等。作为模型计算机设计，将重点放在寄存器级，采取较简单的组成模式，以尽量简洁的设计帮助学生掌握CPU 的基本原理。 此次设计CPU就是为了了解CPU运行的原理，从而完成从指令系统到CPU的设计，并且通过仿真对CPU设计进行正确性评定。(The main function of CPU is to execute instructions, control and complete various operations of computer, including operation, transfer operation, input / output operation, etc. As a model computer design, it focuses on register level and adopts a simpler composition mode to help students master the basic principles of CPU with a concise design as far as possible. This design of CPU is to understand the principle of CPU operation, so as to complete the design from instruction system to CPU, and evaluate the correctness of CPU design through simulation.)
